Abstract
A contactless linear rotary transformer comprises a stator, a rotor and a bearing(9) for connecting the stator and the rotor. The rotor is composed of a shaft (7) and a rotor iron core (8) arranged outside the rotor. The stator consists of a front shell cover (1), a back shell cover (2), a stator shell (3), a stator iron core (4) and a winding (5), wherein the rotor, the stator iron core (4) and the winding (5) are arranged in an inner cavity of the stator shell (3), and the front shell cover (1) and the back shell cover (2) are respectively arranged at the front end and the back end of the stator shell (3). The contactless linear rotary transformer is simple in structure and excellent in technical effect.
Description
Technical field
The utility model relates to the rotating transformer structures design field, and a kind of contactless linear resolver is provided especially.
Background technology
In the prior art, the application of rotation peace transformer is more.It is more simple that people catch at a kind of structure, the resolver that technique effect is more good.
Summary of the invention
The purpose of this utility model provides the good contactless linear resolver of a kind of technique effect.
The utility model provides a kind of contactless linear resolver, and it is specifically by stator, rotor be connected this two-part bearing 9 and constitute; It is characterized in that: rotor is by axle 7 and be arranged on its outside rotor core 8 and constitute;
Described stator is made of following several parts: housing protecgulum 1, housing bonnet 2, stator case 3, stator core 4, winding 5 are formed; Wherein: be furnished with rotor, stator core 4, winding 5 in stator case 3 internal cavities, housing protecgulum 1, housing bonnet 2 are arranged on stator case 3 rear and front ends.
In the described contactless linear resolver, described winding 5 specifically is divided into winding and secondary winding two parts, and winding is by stator core 4, air gap and rotor and secondary winding linkage mutually.
Contactless linear revolver operation principle: at a winding S
1S
2Two ends apply specified alternating voltage U
12, just have electric current to flow into, thereby in stator core 4, air gap, rotor, encourage an alternating flux
φAlong with the field spider anglec of rotation changes, air-gap permeance changes, with the secondary winding magnetic flux of linkage mutually
φAlso respective change owing to the alternation effect and the magnetic flux size variation of magnetic flux, according to the law of electromagnetic induction, finally induces the voltage U with the rotor angle linear change at the secondary winding two ends
34
Advantage of the present utility model: simple in structure, technique effect is good.
Description of drawings
Below in conjunction with drawings and the embodiments the utility model is described in further detail:
Fig. 1 is the structural principle schematic diagram of contactless linear revolver described in the embodiment 1.
